GEAR MECHANlSM AND CONNECTlNG-ROD FOR CONVERTING ROTARY INTO RECIPROCATING MOTION.

SPECIFICATION forming part of Letters Patent No. 233,810, dated October 26, 1880. Application filed March 10, 1880. (No model.)

To all whom it may concern Be it known that I, ALoNzo J ENISON SIM- MONS, of Pana, in the county of Christian and State of Illinois, have invented an Improvementin Gear Mechanism and Connecting-Rod for Converting Rotary into Reciprocating Motion and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying'drawings, forming part of this specification, in which- Figure 1 is a plan view of the four-motioned sliding block, showing, in dotted lines, its general course of movement. Fig. 2 is a longitudinal section of the same as arranged within a housing and connected with its coacting parts. Fig. 3 is an inverted plan view of the sliding block. Fig. 4 is a similar View, showing it with the sliding tongue in place.

My invent-ion relates to a novel mechanical movement for converting a rotary into a rectilinear reciprocating motion; and it consists in the combination of a shaft carrying a pinion with a peculiarly-formed sliding block contained in a housing within which the block slides, which block is formed with an oblong groove and an elongated or elliptical gear on one side, with which the pinion engages, and with a straight groove on the other, which receives the tongue of another sliding block, which is connected to the object to be reciprocated, whereby a rotation of the shaft gives to the first sliding block a four-motioned sliding action, and this in turn transmits a rectilinear sliding action to the second block, to be utilized as required.

In the drawings, A represents a housing or casing, through which there extends a driveshaft, B, which drive-shaft is journaled in a bearing in the housing, and carries upon its inner end a rigid pinion, a.

C is the sliding four-motioned block, which fits loosely between the inner walls of the housing with a free endwise and lateral play. This sliding block is formed on one side with an oblong groove, b, and a central elongated gear, a, formed of two racks with outwardlyprojecting teeth, which turn and run into each her at the ends. In this oblong groove b is arranged a friction roller, f, which turns loosely on the inner end of the shaft B and guides the sliding block, while the pinion on the shaft engages with the elongated gear, giving to the block a longitudinal movement in one direction, then a lateral movement when the ends of the elongated gear are reached, then a longitudinal movement in the opposite direction, and then'a lateral movement at the opposite end of the elongated gear, producing a four-motioned action.

On the opposite side of the sliding block from the gear is formed a groove, 9, which may be either transverse or longitudinal, ac-

cording to the direction in which motion is to,

be taken off, and in which groove there slides the tongue of a block, D, which forms a connection for the object to be reciprocated, and to which block and its connection a reciprocating motion in right lines is imparted at right angles to groove 9.

When a long stroke is required in the reciprocation, as in operating deep-well pumps, the groove in which the block D slides will be transverse, and when a shorter stroke is required, as for operating the seed-slide H of a planter, the groove in block 0 will be longitudinal, as shown.

The mechanical movement as described I propose to apply to any and all uses for which it may be applicable, and it affords a very desirable method of converting a rotary into an intermittent reciprocating motion.

In defining my invention more clearly I would state that I am aware that a block having an elongated continuous set of gear-teeth has been arranged in relation to a rotating pinion heretofore so as to be reciprocated thereby, and I therefore only claim these devices when said block is provided with a groove, 9, underneath the .same, and is combined with a second reciprocating tongued block, D, operating at right angles to the groove, as shown and described. The gear shown and claimed in this case I have also shown in connection with a check-row corn planter, application for a patent for which was filed March 10, 1880. The gear is not, however, claimed, broadly, in such case.

Having thus described my invention, what I claim as new is- The combination, with a housing and a shaft journaled at right angles Within the same and carrying a drive-pinion, ot' a four-motioned sliding block having upon one side an elon- 5 gated or oblong track-groove, b, and gear 0, and upon the other side a groove, g, together with the tongued block D, arranged in the groove g, and moving at right angles to the same, substantially as and for the purpose described.

The above specification of my invention signed by me this 25th day of February, 1880.
